SEPARAIBLE FASTENER.

Application filed January 16, 192,0. Serial No. 351,780.

To all whom t may concern: Be it known that I, FRED S. GARR, a citizen of the United States, and a resident of Newton, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Separable Fasteners, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention pertains to improvements` in separable fasteners, and means and methods of attaching the saine to fabrics.

In the drawings, wherein I have shown a preferred construction of one illustrative embodiment of my invention Figure 1 is an elevation of two pieces of fabrics secured together by separable fasteners;

Fig. 2 is a plan view of a preferred form of socket;

Fig. 3 is a plan view of a preferred form of plate for securing the socket shown in Fig. 2 to the fabric;

Fig. 4. is a side elevation of the plate shown in Fig. 3;

Fig. 5 is a plan View showing the socket attached to the fabric by the attaching plate shown in Fig. 3;

Fig. 6 is a plan view of a preferred form of stud securing plate;

Fig. 7 is a plan view of a preferred form of stud prior to assembly;

Fig. 8 is a side elevation of the stud shown in Fig. 7 prior to assembly;

Fig. 9 is a plan view showing the stud secured to the fabric by means of the studsecuring plate shown in Fig. 6;

Fig. 10 is a sectional elevation showing the stud and socket in engagement, the sections being taken on the line 10-10 of Fig. 1.

I will first describe the preferred form of socket and its attachment to the fabric. Referring to the drawings, I have shown a preferred form of socket including a springcarrying casing providing at one side thereof a disc 18 having an aperture therein through which the head of the stud may pass, this aperture preferably being notched at one side to provide a lateral lock in the general manner shown in my copending application, Serial No. 307,111, filed June 27, 1919, and the casing preferably containing a spring 19, which may' be U-shaped shown in said application, and held in the casing by flanged-over marginal portions of the socket casing.

The preferred form of socket herein shown is adapted to be secured to the fabric without sewing, and preferably without perfora tion of the fabric by rivets, prongs or lthe like, such attachment being secured by squeezing the yfabric under the rim of the socket casing by placing the socket casing i on one side of the fabric, placing the socketattaching plate 20 shown in Fig. 3 on the opposite side of the fabric and Apressing the two together so that the fabric is rst pressed into the .opening in the socket casing and, as the socket-attaching plate 20 increases in diameter as it is flattened, forcing the fabric under the marginal lips of the socket casing.

I preferably utilize a tool in attaching the socket and, where the preferred formof my invention shown in the drawings is utilized, I may conveniently use a pair of pliersassembled as shown in divisionals of this "application Serial Nos. 601,832 and 601,833, filed November 18, 1922.

I will now describe the attachment of the preferred form of stud. The stud-securing Aplate 24;, shown in plan in Fig. 6, is 4preferably dished to provide a recess having inwardly projecting marginal portions. The stud 25, best shown in Fig. 8, is preferably made with a conical base, slotted to permit increase in diameter thereof when flattened.

In securing the stud to the fabric, the stud-securing plate 24 is preferably positioned on one side of the fabric with the stud 25 on the opposite side of the fabric, and the two are pressed together in such a way as initially to force the fabric into the opening in the stud-securing plate, and then, as the stud-securing plate and stud are pressed one towards the other and the stud expands, to provide for the carrying of the fabric beneath the flanged-over lips of the stud-securing plate.

This construction not only provides a very simple and effective method of securing the stud to the fabric, but preferably brings the neck of the stud approximately in line with the plane of the fabric to which the stud is secured, a feature which materially decreases the tendency of the stud to pull away from the socket when stud and socket are subjected. to lateral strain.;

cluding i a casing having a flanged-overy groove or rim, aspring held in said socket bysaid flanged-over rim, and means for' *securingv said socket to its carrying fabric ldeparting from the scope of my invention,

which is best delined in the following claims. l. A stud for separable fasteners having an expansible base plate, and securing means llocated on the opposite side 'of the fabric from the stud, the base of` said stud expan'sible into engagement with said securing j means, with the fabric to'which the stud is y to be engaged interposed between the base of the stud and the securing means.

2. A stud for separable fasteners having a sloping base, said base split to permit an increase inthe diameter of the base when flat,

and a cooperating stud-securing element providing a recess for receiving theperiph- `ery of the base of the stud whenk expanded,

the fabric t0 which the stud is secured passing between said securing means andthe periphery of said base.v

3@ A' socket for separable fasteners inand including an expansible part adapted to expand and press the carrying 'fabric beneath said ilanged-over riin.,y

4. A separable fastener comprising, in combination, a stud 'and a socket, said socket lsecured to the fabric by an expansible securing plate, said socket containing a spring -ing a dislied plate providing a flanged rim,

a spring held in said socket by said flanged rim and'means for securing the socket to a carrying fabric including an eiipansible plate adapted to expand and to crowd the carrying fabric beneath said flanged rim.

6. A socket for separable fasteners having a dislied plate providing a flanged rim, a spring held in said socket by said flanged rim and means for securing the socket to a carrying fabric including an exp'ansi ble plate adapted toexpand and to crowd the carrying fabric beneath. said flanged rim at points wheresaid flanged rim does not overlie said spring. v

l 7. `lncombinatioii with a metallic secured lseparable fastener, a stud; a socket having a plate and a notched aperture therein, said notched aperturev providing a lateral lock against separation of stud and socket by a resolution of forces arising from lateral strain 4inthe general direction of the notch; and means for metallically securing the socket to the fabric, said means insuring the positioning` of the notch in adjacency vto the edge of the fabric lt0 which the socket is applied. n

In testimony whereof, I have signed my name to this specification.
